Application filed December 18, 1924. Serial No. name.

To all whom it may concern:

Be it known that I, WILLIAM G. Kerr, a citizen of the United States,residing at Oakland, in the county of Alameda and State of 5 California,have invented certain new and useful Improvements in Bumpers, of whichthe following is a specificatio The present invention relatesto bumpersfor automobiles and other likelvehicles.

an improvement in bumpers of the nonhook type, which improvementconsists essentially in the particular construction of the central ormain contact bar and the mounting brackets extending therefrom, and alsoconsists in the formation of the nonhook ends and their manner ofattachment to the ends of the main bar, whereb a stronger and moreefiicient bumper of t is type is provided.

With the above mentioned and other ob 'jects in view, the inventionconsists in the novel construction and combination of parts hereinafterdescribed and illustrated in the accompanying drawings and pointed outin $5 the claims hereto appended, it being understood that variouschanges in form, propor-v tion, size and minor details of constructionmay be resorted to without departing from the spirit'or sacrificing anyof the advan- 3 t es of the invention.

0 more fully comprehend the invention, reference is directed to theaccompanying drawings, wherein- Figure 1 is a fragmental plan view ofthe i front end of an automobile showing the bumper attached thereto.

Figure 2 is a fragmental plan view enlarged showin one of the hingedmembers, in art only, t e rear face being omitted.

igure 3 is a vertical sectionalview taken inthe direction of the arrowson line 3-3 of Figure 2.

In the drawings, wherein like characters of reference designate 7corresponding parts, '1 indicates the central melhber of the bumper,constructed preferably of flat strap material, the ends 2 of which areturned backward and form a meansof securing the cantI al member 1 to-theframe horns 3 of the chassis of an automobile by means of the bolts 4'or other suitable attachiniedevices. The outer faces of the rearwardlyThe object of the invention is to produce forwardly onl nt ends I 2 alsoform an abutment against which the their front faces 6 being shaped tocontinue the contour of the front face of the central member 1theirrear'faces 7 being inclined toward the apex, as shown in Fig. 1,and

their base faces 8 lying parallel with and abutting a ainst the outerfaces of the bent ends 2 of t e central member 1.

.The triangular end members 5 are secured to the ends of the centralmember 1 by means of a spring hinge 9, the tension of the sprin beingsufiicient to hold the triangular end members 5 substantially rigidagainst the abutments formed by the bent ends 2 of the central member 1.

The operation of the end members 5 when struck by an impact from therear is such that said members will yield forwardly to permit thevehicle to pass the obstruction, thus eliminating any possibility of thebumper being caught and displaced or injure V After the obstruction haspassed the end members 5 are returned to their normal position'due tothe tension of the springhinge 9.

On the other hand, if the force of impact comes from the front, the samewill be met by substantially rigidresistance due to the relativelyextensive and solid abutments 2 and 8.

I claim l. A bumper comprising a central member having rearwardl v bentends adapted for attachment to ave 'cle frame; end members consisting ofsubstantially triangular sections the front faces of which are shaped tocontinuethe face contour of the central member,their rear faces beinginclined forwardly to an a x, and their base faceslymg parallel withand. abutting a ainst the outer faces of the bent ends of t e centralmemher and a spring hin e connection between said end membersan the endsof the central member located in the line of their front faces, adaptingsaid end -membersto,
